'OSCILLATING-CYLINDER PRINTING=NIACHINE.

SPECIFICATION forming part of Letters Patent No. 432,518, dated July 22, 1890.

Application filed September 2, 1889. Serial No. 322,801.

To all whom t may concern:

Be it known that I, PELEG S. DODGE, acitizen of the United States, residin g at Stanton, in the county ot' Montcalm and State of Michigan, have invented certain new and useful Improvements in Oscillating-@yhnder Prin ting- Machines; and I do hereby7 declare thevfollowing to be a full, clear, and exact descript-ion of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to a printi ilgpress, and more especially to that class of printingpresses wherein anl oscillating im pression-cylinder is employed, in combination with a reciprocating type-bed, the latter being reciprocated coincidentally with the oscillation of the former; and the object of my invention is to provide a cheap, si mple. and effective printing-press having an oscillating cylinder and reciprocating type-bed actuated, by means of the ordinary crank, by either hand or steam power, the driving-shaft having a continuous forward movement, the sheet-s being delivered without contact of the freshly-printed matter with any part of its operative mechanism; and it consists in the construction, combination, and arrangement. of the parts, hereinafter described, and more particularly pointed out in the claims, reference being .had to the accompanying drawings, in whieho Figure l is a side elevation of the driving side of my press with part of the frame broken away; Fig. 2, a side elevation of the opposite or feeding side; Fig. 3, a transverse vertical section on the line X X; Figs. at and 5, details showing method of securing cable to cylinder.

A represents the main frame of the machine; B, the type-bed, mounted on usual rolls 40 and ways 40', (shown in Fig. 3,) and C the impression-eylinder. A

C is the head of the impression-cylinder, the face of which is a mangle-wheel having its axis eccentric to the axis of the said cylinder, and provided with pin-cogs K for engagingY with pinion L on the drivingshaft M, the end of said shaft being adapted to traverse the mangle-groove 3 for imparting an oscillating (No model.)

mot-ion to the cylinder by means of a continuous rotary motion of the driving-shaft., to which the hand-crankA P is attached. The drivingshaft M is mountedin vertically-movable bcarings N, moving in ways O.

The impression-cylinder C is mounted on and rigidly secured to the shaft S, which is journaled in eccentric-sleeves R, and is provided with collars T. The eccentric-sleeves R are journaled in vertically-adj ustable bearings Q, and the collars T, secured to shaft S, have lugs U for engaging the pins c c on the sleeves R and operating said sleeves and the latches ly y.

It will be understood that the parts described are paired and arranged at opposite ends of the cylinder for operating simultaneously.

Each of the latches g/ y is provided with a notch e' or .e,which engages the pinVand keeps the sleeve from rotating, and the latch y' is provided at its free end with a weight w, which weight tends to keep said latch in its lowermost position. To the sleeve R is rigidly secured the arm l, and to the rock-shaft 2O is also rigidly secured the arm l. These two arms are connected by the rods 2 for causing said sleeves, arranged at each end of said shaft S, to operate in unison. The tendency 0f the weight \V, arranged on the arms l', is to throw the full part of the sleeve to the left, thus lifting the impression cylinder and throwing itslightly upward and to the right, causing it to occupy the position indicated by the dotted lines in Figs. land 2 for clearing the type bed and engaging the delivery parts on the return-stroke.

D is the platform for the paper; 12, the feed-board hinged to the platform.

E are the delivery-tapes; F, the fly; Gr, the ink-fountain. l

II is a cable, having its opposite ends attached to adjustable posts t, provided with tension-screws 5 and secured to the respective I is the friction-heel which drives the tapes and to which motion is intermittingly imparted by the head C.

.l is the belt connecting the friction-wheel with the tape-roll 2-1, having a brush 25.

6 is an arm pivoted to the main frame, and 7 a screw foradjustingthelength of said arm. 8 is also an arm pivoted to the frame having a roll f), iournaled thereon, which serves as a fulcrum :for the lever l0, which has its inner end pivoted to bearings N, and has the outer arm curved and provided with weight XY'.

1l is a U-shaped dog having one arm extended for engaging the end of arm S, and is secured to the side of the type-bed for shifting the fulcrum 0, and thus forming a variable counter-balance for the movable bearings N.

l5 is the lever operating the ink-fountain roll, and is connected by the rod ll to the sliding bar 3G, provided with the post 36', which slides on the frame, and is actuated by the type-bed B striking the said post 3G'.

17 is a wheel which aetuates the shaft operating the fly F, and is put in motion by the bed B through and by means of the strap 1G and sliding bar 35, having post 35', which is engaged by the bed at the proper moment. The bars 35 and 3G are, as shown in Fig. 3, located side by side and separated by a partition 3G? 1S is the adjustable hanger for the wheel l, and is provided with adj listing-screw 1).

2l is the return-cam for the fly, having act uatinfr-spring 2? and connecting-strap 2t is the gripper, and 27 the gripper-shaft; 2S, the lever that operates the grippers; 29, the spring which holds the gripper-lever in position.

30 is a pin arranged at the end of the griplever, and which engages thearm 39 for opening the gripper to release the sheet.

231 is a pivoted arm having' lateral projections 33 and Si, having faces adapted to engage the pin 30 for operating the grippers to seize the sheet, and is provided with a stoppin 32.

37 is a rod connecting the feed-board l2 with the arm l' for alternately raising and lowering the feed-board.

t2 is a lifter for the latch g/ for throwing off the impression, and has stop-pins .3S for limiting its movement.

-ll is the channel in the periphery of. the cylinder containing the gripper-shaft 527.

The general operation of the machine is as follows: lowerbeing applied to the crank l), the shaft M is caused to rotate, and its motion being transl'nitted by pinion L to pincogs K causes the cylinder C to rotate in either direction, and the cylinder C being attached directly to the bed i3 by cables li the bed is reciprocated coincidentally with the oscillation of the cylinder. ly placing the axis of the mangle-whcel eccentric to the axis of the cylinder I obtain an accelerated motion at the middle of the stroke and a slower motion at the end of' the stroke for overcoming the inertia of the reciprocating parts, thus avoiding the necessity for buffers, and by using the long curved lever ,l0 provided with its shifting fulcrum, l provide a counter-balance for the movable bearing N. ln the illustration the position ot' the parts when at about the middle of the printing-stroke is shown, the impression-cylinder being rotated in the direction indicated by the arrows. The impression or printing stroke of the cylinder is delivered while the end of the shaft M is traversin g the outer groove of the mangle and the return or non-printing stroke when it is traversing the inside groove. The sheet having been taken from the feed-board, held by the grippers 2G, passed over the types, printed, and occupying a portion of the periphery of the cylinder C is brought to a height sutlieient to make it enter upon the brushes 25 at the commencement of the non-printing stroke. Just prior to the end of the printing-stroke of the cylinder the revolution of shaft S brings lug U' into engagement with latch Y', disengages it from the pin 7', and the eccentricsleeves R being now free to turn are carried forward by the lugs U U', engaging with the pins V V', to the end of the stroke, shifting thc position of shaft S, and thus shifting the axis of the impression-cylinder obliquel y upward and forward to the position indicated by the dotted circular line, when the notch ,e in the latch 1/ engages the pin 'v and holds the cylinder in its new position d uringthe return or non-printing stroke free from the type and in frictional contact with wheel I. The head C', engaging wheel I, sets the revolving brushes and tapes in motion. The brushes engage the tail of the sheel,bringing it upon the tapes, by which it is run backward over the fly F. The arm 39 being in its lower position now engages pin 30 and depressing the lever 28, opens the grippers, relieving the sheet. The tapes, running faster than the cylinder, remove the sheet from beneath the grippers before they close. Near the termination of the return-stroke the type-bed comes in contact with the post 35' and operates the fly, depositing the sheet upon the table D'. During the return-stroke the feed-board is in its lower position. The sheet is fed over the same into the gages 13, resting on the hooks at the end of the gages. During the latter part of the return-stroke the lug U disengages the latch q/ and engages the pin c, and rcstoresthe cylinder to its former position preparatory to the printing-stroke, re-engaging the latch 'y' for holding the cylinder during the printing-stroke. The revolution of the eccentric R by raising the arms l l, which have connection with the feed-board, raises the feed-board and brings the edge of the paper nearly in contact with the periphery of the cylinder. Just prior to the termination of the return-stroke the piu 30 strikes IOO IZO

the incline 33 and is forced toward I(he axis .of the cylinder, thus opening the grippers,

beginning of the printing-stroke the pin 30 lpasses under the inclines 33 and Si, lifting the arm 3l oif the pin 32, thus permittingthc grippers' to retain their hold on the papell by the action of the spring 2. during the printing-stroke and until released, as described. Lever 15,0perating the foui'itain-roll, is moved in one direction at the end of the returnstroke by the type-bed coming in contact with the post 3G', which slides the bar 36, connected to lever l5 by rod 14, in its bearings, and is restored to its former position by the weight IV.

The devices for inlring the types are not shown, for the reason t-hat those employed are such as are common to machines of this class.

The pivoted arm G, having adj Listing-screw 7, is employed when it is desired to use the press for taking proofs by adjusting it underneath the lever l', so that when the lever l is depressed it will rest on the top of the screw 7. The cylinder C is raised off the type just enough to accommodate the galley-bottom, and by rotating the cylinder the same as in printing a proof may be taken off.

For securing the cable to the cylinder I provide two parallel grooves extending entirely around the periphery of the cylinder at one end. At a point about opposite the chamber containing the gripper the ridge between the two is cut away, and at that point I arrange a tie-pin h, firmly secured below the surface of the periphery and extending across the groove at right angles to it. Having secured one end of the cable to one of the posts on the typelbed, I pass it under and over the cylinder in one of the grooves. At the point where the cable crosses t-he tie-bar I take a turn of said cable around said tiebar, causing the cable to pass from one across into the opposite groove, as shown in Fig. 5, and extend it on' around the cylinder in that groove, attaching the end to a post at the opposite end of the type-bed, thus forming a permanent means of attaching the cable and preventing it from slipping.
